DRAWING OF THE WARP TH'RGUGH THE REED.

Application filed March 19, 1923.

T 0 all w from it may concern.

Be it known that I, SVEND SIGURD CHRIS- TIE FLnIsoHER, a subject of the King of Denmark, residing at 5 Christinelundsgatan, Gottenborg, Sweden, have invented certain new and useful Improvements in the Drawing of the Warp Through the Reed, of which the following is a specification.

The drawing of the warp through the reed, when preparing to weave, is generally done by two workmen, the one of them holding the warp in his left hand behind the reed and handing over the warp to the other workman, who introduces a hook in the opening between two of the reed strips, catches a thread, and draws it through the opening and so forth for each opening in the reed.

My invention has for its object to simplify this operation. My invention consists chiefly in that a hooklike member or more members are mechanically moved in such a way that the said member is introduced through the reed opening so as to appear on the rear side of the reed and is returned to the front side through the same opening, then is introduced through the following opening and so forth. Each time when being at the rear side of the reed the member receives a thread or a desired number of threads. In this way the drawing-through of the warp is essentially quicker than by the ordinary method and is. done by a single workman, the work now merely consisting in placing the threads in the member or members and perhaps to move the member or members e. g. by acting on a pedal or the like or by closing an electric circuit or in another suitable manner.

In the most preferred form for an apparatus according to my invention the memher is provided with oblique or bent wings, laps or the like which through their action on the strips of the reed during or after the drawing-through-movement, automatically cause a movement of the member parallel to the reed so as to bring the member in position opposite to the following openmg.

A form of construction of an apparatus according to my invention is by way of an example shown diagrammatically on the annexed drawing. Figs. 1 and 2 show an end view and a plan view respectively.

The reed indicated at 3, is placed, with the rear side upward, on a suitable support Serial No. 626,216.

such as a frame 5 consisting of two angle 8 which can engage the one angle iron, and

another longer and adjustable hook 9 for engaging the other angle iron. The branches of the body 7 form bearings for a shaft 10, which between the branches has a polygonal or other suitable section permitting the drawing-through-member 11 to be mounted on it in a slid-able but not turnable manner. The member 11 is a circular disc the circumference of which by cuts is divided in asmaller part 11" forming a nose 11 and a greater part 11 having an open eye 11 at the one end for receiving the warp thread and at the other end, a nose 11 opposite to the nose 11 The nose 11 is bent laterally so as not to be in the same plane as the parts 11 and 11. A spring 12 is connected with and tends to turn the shaft in the one direction, while by pulling a band 14; on a roll 13 the shaft is turned in the opposite direction, the turning of the shaft in both directions being limited by a pin 15 or the like. The hand is connected with a stirrup (not shown) or the like enabling the workman to turn the member in the one di rection with the foot. By this turning the greater part 11 with the eye 11 protrudes on the rear side of the reed and when the warp thread is placed in the eye, the workman ceases to press on the stirrup so as to enable the spring to turn the member back. By this back turning the warp thread is drawn through the reed, the eye now going over on the front side of the reed. Simultaneously herewith the laterally projecting I nose 11 acts on the strip of the reed with which it comes into contact so as to move the member 11, a short distance along the shaft 10, the movement being upward with the parts in the position shown in Fig. 2 enabling the nose 11 to enter the following opening of the reed so that the member when reaching its stop position, lies opposite to the opening adjacent to that one through which the thread just have been drawn. Hence the workman when pulling introduces the part 11 with the eye 11 in the new opening which now can be threaded and so forth.

A screw or the like 16 permits the body 7 to be placed more or less oblique to the am gle iron and by that the member 10 is brought to correspond to finer or coarser reeds.

In the example shown on the drawing the draWing-through-member is intended to be turned a certain angle forward and back- Ward, but I Wish to point out that the member can be constructed so as to work by rota tion only in the one direction moving itself a little during or after each drawing-throughoperation.

Further, in the example shown on the drawing the drawing-throuohanembcr ii is rotated about the axis along which it is sliding. Of course the member 11 may be turned about'one axis and slide along another axis, which latter partakes in the swinging movement.

As these alterations may be understood Without further explanation I have not illustrated them on the drawing.

The parts of the drawing-through-meinber nominated as noses may be elastic or hinged on the member and influenced by a. spring or the like.

Of course the support which I have described as a frame formed by angle irons, can be altered in many different ways, and likewise the other details.

- hat I claim is 1. In a reeding machine, a reed support, a shaft jonrnaled on said support, a drawing-through member slidably and non-rotatably mounted on said shaft, means for im parting oscillatory movement to the shaft and drawing-through member, said drawingthrough member having a thread receiving eye therein, and means carried by said drawing-through member adapted to co-act with the strips of a reed to move the drawingthrough member longitudinally along the shaft, step by step incident to the successive oscillations of said shaft.

2. In a reeding machine, a reed support, a shaft rotatably mounted on said support, a drawing-through member slidably and nonrotatably mounted on said shaft, means for oscillating said shaft back and forth through a predetermined angle, said drawingthrough member having a thread receiving eye therein and having a portion thereof bent laterally to coact with the strips of a reed whereby to advance the lll:l\\lll l through member step by step longitudinally of the shaft incident to successive oscillations of said shaft.

3. A. reeding machine as claimed in claim 1 characterized by the provision of means for varying the angular position of the shaft with relation to the reed support.

4. In a reeding machine. a reed support, a rotatable shaft, a drawing-lbrough member siidably and non-rotate:lily mounted on said shaft having a thread reccirin at eye therein, means on said dra ving-throlurh member adapted to coact with the strips of a reed whereby to move the drawing-chrough device longitudinally along the shaft. step by step incident to successive oscillations of the drawing-through member, means for effecting the oscillatory movement of the drawing-through member, a frame structure rotatably supporting: the shaft and. mounted on the reed support, and means for varying the position of the frame structure relative to the reed support.

In a reeding machine, a. reed support, a frame structure mounted on said reed support, a rotatable shaft mounted in the frame structure, a drawing-through member slidably mounted on said shaft and adapted to successively enter the spaces between the strips of a reed disposed in the reed support, and means for varying the position of the frame structure relative to the reed support.

6. In a reeding machine, a reed support, a frame structure mounted on said reed support, a shaft journaled in. said frame structure, said frame structure including mom hers loosely embracing the reed support; and permitting limited movement of the frame structure relative to said reed support, means for varying the position of the frame structure relative to the reed support, and a drawing through member slidaliily mounted on the shaft and adapted to successlvely enter the spaces between the strips of a reed disposed on the reed support.

In testimony whereof I hereunto allix my signature.
